Injection point: what it means in HOF

An injection point is the spot on the skin where the product is introduced or deposited. With botulinum toxin, each point receives a fraction of the total dose, spread over the muscle to be relaxed. With filler, the point can be the exact spot of the deposit, when a needle is used, or the entry port from which the cannula travels through the area.

The number and position of points vary with the patient's anatomy, the product, the goal and the chosen technique. There is no single map: muscles differ in size, strength and insertion from person to person, and it is the clinical assessment that defines where to inject.

Why record the injection points?

Recording the points, the dose or volume at each one and the product used helps to:

• compare the result with the previous session and adjust the plan;
• investigate an asymmetry or a complication more clearly;
• keep the patient record complete, which is the professional's duty.

With toxin, for example, the record usually includes the amount in units per point. Standardized before and after photographs complement this record.

In Harmy

On the marking screen, Harmy shows labeled points on the face, such as Glabella, Cheekbone and Lips. These points are treatment areas, not injection points: they tell the projection where the change should appear and are used to build the plan in ml per area. The technique and the actual injection points are left to the professional's judgment.

Also called: injection site, entry point (in the case of the cannula).
